Abstract

A method comprises the steps of obtaining a baseline measurement corresponding to a representation of brain activity from a living body and storing the baseline measurements on a storage device configured to be wearable on the living body in combination with obtaining, at a time subsequent to the baseline measurement, a second measurement representing brain activity from the living body, reading the baseline measurement from the storage device and evaluating the living body based on a comparison of the second measurement to the baseline measurement. A system for analyzing electrical brain activity, the system comprises a component for reading, from a storage medium, data corresponding to a baseline measurement of brain activity of a living body and a component for determining data representing a current brain activity of the living body in combination with a component for evaluating the living body by comparing the baseline measurement data and the current brain activity data.
